#property strict should be added, after that the date output will be in "yyyyy.mm.dd hh:mm:ss" format even without conversion.

or TimeToString(TimeCurrent(),TIME_DATE|TIME_SECONDS)

Looks like it's not that simple, or is there something I don't understand?

As a version, the dog is buried in the indicator buffer, as it is a type double.

Good afternoon, comrades!

This is the first time on the forum, so don't kick me if this is an old-fashioned question...

How to open trades in cycle after a certain interval (every minute, for example) ?

In advance, thank you

Why do you put the string in the indicator buffer?

By checking the opening of a new bar of the appropriate TF!

Hello, I have this question:

MT4 has great possibilities for expert optimisation, but is there any tool to optimise indicators? If I want to optimize an indicator's parameters so that its readings were maximally "correct", is it true, that the only way to do it is to write an ekspert on its basis and run it through the history?

And I also would like to know if MT-4 has a custom criterion of optimizing of Expert Advisors like in MT5?

 

Guys I forgot...

How to get an array of current orders and loop through it. And loop to get the order information. MT4, thanks...

Why do you shove the string in the indicator buffer?

I understand the absurdity of this action, but I don't understand how to use the indicator

display bar time in the terminal data window in the format "yyyyy.mm.dd" and "hh:mi" (as the first and second lines in the terminal data window)

The indicator buffer will either output the time in seconds from 00:00 1 January 1970 by assigning to it time[i],

or after conversion(TimeToString) truncated date or time.

And if there is a possibility to display it using custom MQL tools, advise how to do it? Thanks in advance!

but if you explain it, maybe we can understand and explain it to you.
